WHY GENE CENTRIC PROTEOME PROJECT IS REALISTIC? • RECENT PROTEOMICS IS GENOME-BASED SCIENCE. GENE CENTRIC PROJECT IS APPLICATION OF EXISTING TECHNOLOGIES TO SIMPLIFYED TASKS
• CREATED MRM/IRREVERSIBLE BINDING TECHNOLOGY ALLOWS TO ANALYSE BLOOD PLASMA PROTEINS WITH SENSITIVITY 10-18M (1 copy/1µL) OR 1 PROTEIN COPY PER 103 LIVER OR HEP2G CELLS . • • FOCUSED MRM ANALYSIS OF SINGLE CHROMOSOME WITH KNOWN GENE NUMBER ALLOWS TO GENERATE “GOLD STANDARD” FOR GENE CENTRIC PROTEOME PROJECT. • Molecular recognize mapping (MRM) CRITERIA FOR CHROMOSOME SELECTION:
• TOTAL NUMBER OF PROTEIN-CODING GENES • CLINICAL RELEVANCE • NUMBER OF ALREADY IDENTIFIED PROTEINS • ABSENCE OF IMMUNOGLOBULINS CHROMOSOME STATISTICS

PRIDE = 224 identified proteins Protein Atlas = 102 proteins PRIDE (PRoteomics IDEntifications database) 48 PROTEINS – NOT CONFIRMED In Protein Atlas only In PRIDE only (12) (134)
In PRIDE and in Protein Atlas (90) How many proteins can we expect for 18th chromosome?
285 Trancriptome analisys of 18th chromosome + 230 Over 80% of the genes undergo alternative splicing (Kampa at. al, Genome Res., 2004, 14, 331-342)
516 On average, each of them can have 50 PTMs x 50 (Nielsen M, Savitski M, Zubarev R, MCP, 2006, 5, 2384-) Protein species can be expected as expressed in HepG2 cell line 25800 HepG2 cell lines ซึ่งเป็นต้นกำเนิดจำกมะเร็งชนิด hepatocellular adenocarcinoma ROADMAP
PROTEOME OF THE 18-TH HUMAN CHROMOSOME: GENE CENTRIC IDENTIFICATION OF TRANSCRIPTS, PROTEINS AND PEPTIDES
http://www.proteome.ru/en/roadmap/ http://www.hupo.org/research/hpp/soc/ RusHPP CONSISTS OF TWO PHASES: GOAL OF THE PILOT PHASE IS IDENTIFICATION OF ALL MASTER PROTEINS PRODUCED BY 18thCHR IN LIVER AND HEP2G CELLS AND IDENTIFICATION OF THEM IN PLASMA WITH SENSITIVITY 10-18 M (1 PROTEIN COPY/ΜL ) AND 1 PROTEIN COPY PER 103 LIVER OR HEP2G CELLS. MAIN PHASE OF RusHPP
THE GOAL IS THE IDENTIFICATION OF ALL MODIFIED PROTEINS(ABOUT 30000) EXPRESSED BY 18CHR AT SENSITIVITY 10-18 M.
BIOINFORMATIC AND EXPERIMENTAL CREATION OF 18THCHR PROTEIN INTERACTOME BY COMBINING OF OPTICAL BIOSENSOR WITH MS (BUNEEVA O. ET AL. PROTEOMICS 2010, 10, 23-57.)
CREATION OF 18THCHR PROTEIN KNOWLEDGE BASE PRINCIPLE DIFFERENCE BETWEEN GENOMIC AND PROTEOMICS
PRINCIPLE DIFFERENCE BETWEEN GENOMIC AND PROTEOMICS IS EXISTENCE OF POLYMERASE CHAIN REACTION (PCR) IN GENOMICS ALLOWING TO MULTIPLY NUCLEIC ACID MOLECULES AND ABSENCE OF PCR-LIKE REACTION IN PROTEOMICS. DUE TO PCR GENOMICS DOES NOT HAVE DETECTION LIMIT (DL) OBSTACLE. PROTEOMICS HAS IT. THREE BOTTLENECKS OF HPP • LOW SENSITIVITY OF RECENT PROTEOMIC TECHNOLOGIES. THE BEST ONE -- MRM-MS REACHES SENSITIVITY UP TO 10-14 M*, CORRESPONDING TO 10 000 PROTEIN COPIES IN 1ΜL OF PLASMA. • THE ABSENCE OF “GOLD STANDARD” FOR SAMPLES AND SAMPLING. • PROTEOMICS IS SITUATIONAL SCIENCE. WHAT IS BOARD LINE BETWEEN DIFFERENT SITUATIONS ?? WHAT IS REVERSE AVOGADRO’s NUMBER ?
23 NA=6.022x10 MOLECULES/MOLE 1 MOLE - 1L - 1M -24 1/NA≈10 MOLE/MOLECULE ≈1MOLECULE/L = 10-24 M
[Archakov A.I. et. al. PROTEOMICS 2007, 7, 4–9] IT WOULD BE POSSIBLE TO INCREASE THE SENSITIVITY UP 10-18M [ARCHAKOV ET AL., 2009], CORRESPONDING TO 1 PROTEIN COPY IN 1ΜL. IT BECAME ACHIEVABLE DUE TO COMBINING AFM OR MRM TECHNOLOGIES WITH IRREVERSIBLE BINDING OF PROTEINS TO BRCN- SEPHAROSE. ** atomic force microscopy (AFM) and magnetic resonance microscopy (MRM) THE SENSITIVITY AT THE RANGE OF 10-18M WILL BE QUITE ENOUGH FOR STARTING THE HPP.

1. ANALYTICAL COMPLEX BASED ON THE COMBINATION OF ATOMIC FORCE MICROSCOPY AND MASS- SPECTROMETRY
2. ANALYTICAL INSTRUMENTS BASED ON NANOWIRES
3. INFORMATIONAL CLOUD COMPUTING SYSTEM BASED ON THE PERSONAL SUPERCOMPUTER PLATFORM WHAT IT MEANS PROTEOME-BASED MEDICINE? 1. NEW DIAGNOSTIC TESTS BASED ON HIGH SENSITIVITY TECHNOLOGY SOLUTIONS (1A) AND PROTEOTYPING (1B) WILL BE CREATED.
1A. UP-TO-DATE METHODS HAVE SENSITIVITY ABOUT 10-12 M. IT MEANS, THAT 1 BILLION OF PROTEIN COPIES COULD BE DETECTED IN 10L OF BIOLOGICAL MATERIAL. IF SENSITIVITY INCREASE UP 10-18 M WE COULD DETECT 1 PROTEIN COPY PER CELL.
1B. AS THERE EXIST SNP, SAP, AS AND PTM, THE TOTAL NUMBER OF PROTEINS ENCODED IN THE GENOME (~20,000 GENES) COULD INCREASE UP 2 MLN. PRESUMABLY, THESE UNKNOWN PROTEINS CAN BE USED IN DIAGNOSTICS.

2. NEW DRUG TARGETS THERE ARE ABOUT 500 DRUG TARGETS NOW IN USE IN PHARMACOLOGY. AT THE END OF HPP AROUND 5 000 - 10 000 NEW DRUG TARGETS COULD BE FOUND.
3. NEW MOLECULAR MECHANISMS OF DISEASES DEVELOPMENT WOULD BE DISCOVERED IDENTIFICATION OF THOUSANDS OF NEW PROTEINS WOULD HELP TO DECIPHER THE COMPLEX METABOLIC PATHWAYS AND REVEAL UNCOMMON INDIRECT PROTEIN-PROTEIN RELATIONSHIPS. ACKNOWLEDGEMENTS
